PARIS: Scientists on Tuesday revealed the “highly unusual” behaviour of a male monkey filmed trying to have sex with female deer in Japan -- a rare case of inter-species nookie.

Sex between animals from different species is uncommon, but exceptional cases are known to occur, chiefly in domesticated and captive animals, scientists reported in the journal Primates.
